What transphobic slur? Hermaphrodite? That's a biological term for when an organism has the reproductive organs of both sexes. So it does not relate to transsexuality and it's not a slur. Unless people started wrongly using it that way of course.
This user is such a goddamn loser. It is true that that H-word is used in like, plant study to indicate what it means, but because it has a long and extremely offensive history of being used to describe intersex people, it is not generally considered to be acceptable to say.
